Slider, head assembly, and disk drive unit

A head assembly, comprising:

• a slider facing a disk-like recording medium and enabled to support a head for reading data from and writing data to the disk-like recording medium;
• an actuator for supporting and moving the slider relative to the disk-like recording medium;
• wherein the slider includes:
• a slider body having a leading edge and a trailing edge disposed at a predetermined interval therebetween in a rotational direction of the disk-like recording medium, an inner edge and an outer edge disposed at a predetermined interval therebetween in a radial direction of the disk-like recording medium, and an air bearing surface formed among the leading edge, the trailing edge, the inner edge, and the outer edge;
• a cross rail formed along the leading edge;
• side rails extended from ends of the cross rail toward the trailing edge;
• a first pad formed between the cross rail and a boundary between the side rails and enabled to give a positive pressure to the slider;
• landing pads formed at the trailing edge;
• a center rail formed between the landing pads;
• and
• a second pad formed on the center rail and enabled to give a positive pressure to the slider.

A disk drive unit, comprising:

• a disk-like recording medium being driven rotationally around a rotary axis and enabled to record data thereon;
• a slider provided with a head for writing data to and reading data from the disk-like recording medium;
• an actuator for seeking the slider relative to the disk-like recording medium;
• an enclosure for housing the disk-like recording medium, the slider, and the actuator;
• wherein the slider includes:
• a slider body provided with a leading edge, a trailing edge, and an air bearing surface formed between the leading and trailing edges;
• a U-shaped rail formed on the air bearing surface having a cross rail at the leading edge and a pair of side rails extending from the cross rail toward the trailing edge, each of the side rails having a tip that extends toward the trailing edge;
• a pad formed on each of the side rails adjacent to the cross rail to define a pair of pads;
• a center rail formed adjacent to the trailing edge separate from the cross rail and having a pad;
• a pair of landing pads formed between the tips of the side rails, the center rail, and the trailing edge;
• wherein
• one of the landing pads, which is disposed at an outer periphery side of the disk-like recording medium, is provided with an inclined plane inclined in a width direction, and faces the leading edge.
